Correlation Coefficient Calculation and Simulation in Antenna Diversity

Smart antenna is the critical technique of the third mobile communication, and will become the key technology in the fourth generation communication. The benefits of pattern diversity increase as the incoming pattern distribution becomes more isotropic, so that the research on correlation coefficient in antenna diversity is very critical. This research reviews the related definitions of antenna diversity as well as the related parameters, and then introduces our algorithm to develop closed form solution to calculate correlation coefficient, which provides a generalized method of determining the efficacy of an antenna diversity system. The correlation coefficient calculation is simulated with MATLAB. The simulation results show that the method is efficient and flexible, which will serve as a design tool when constructing pattern diversity systems.
